IPC: H01L21/3065
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a semiconductor device, capable of selectively opening a precise microscopic hole for connection in a silicon oxide. SOLUTION: A microscopic connecting hole is formed in a silicon oxide film 102, through plasma etching with a mixture of a fluorocarbon compound expressed by a general formula CmFn (where m and n are natural numbers expressing atomicity and fulfil the requirement m>=2, n<=2m), oxygen, and an inert-gas such as Ar gas. The etching process of the silicon oxide film 102 is divided into two processes: a partial-etching process just prior to exposing an active substratum material layer and an over-etching process after that, a microscopic connecting hole is opened in a silicon oxide film by decreasing the content ratio of the inert gas to the composition of an etching gas in the over-etching process.

This compressed air is forced out of a discharge piping 10 of a lower cap 3. The pipings 9, 10 are disconnected from the caps 2, 3 and the column 1 is turned 180 deg. and inverted. The piping 9 and the cap 3 are then connected and the cap 2 is held open. The compressed air is blown from the piping 9 into the column 1 to force the packing material out of the column. Since the solvent is first forced out then the packing material is forced out, the splashing thereof is prevented and the compacted packing material is easily taken out.
